Question:how do you make a 3d earth layers science project out of styrofoam how and with what do you cut styrofoam with?

Answers:You could get a giant styrofoam ball, cut it in a cross section and paint in the layers. It's best to use a box cutter when cutting the ball in half. Here's a diagram to go by: http://www.mgm.monschau.de/seismic/images/artikel/abb10_gross.jpg Then in the background get a laptop or a projector and display Google Earth http://earth.google.com/ Then you can download these features to show different layers in an interactive 3D environment! http://www.eastchester.k12.ny.us/schools/hs/teachers/fermann/GE.htm Good Luck on your project, any questions feel free to ask me.

Question:every reference says something else about the number of layers of the atmosphere and the Earth itself, some say 7, others 5, others less. Some say it depends on the way you decide what a layer is. I've been told scientists disagree on how many layers both in the atmosphere and below, so what can I do? is there a good reference that would explain all the confusion? please help

Answers:The wikipedia site for the Earths atmosphere is good (with a nice pic) http://en.wikipedia.org/wiki/Earth%27s_atmosphere As it explains on there, there are the 5 main layers of the atmosphere: troposphere, stratosphere, mesosphere, thermosphere, exosphere. However within those 5 layers there are also subdivisions of layers (like the ozone layer, or planetary boundary layer) that have different physical and chemical properties. It's just really how detailed you want to get! For the earths layers below the surface the main ones are the crust, mantle (which can be divided into the upper and lower mantle), and the core (which can again be divided into the inner and outer core). A nice basic site is http://scign.jpl.nasa.gov/learn/plate1.htm Websites are going to differ depending on their perspective and compexity. For example a scientist working just on the lowest layer of the atmosphere (troposphere) is going to have subdivisions within that. Again, an atmospheric chemist that looks at the atmosphere from one viewpoint may use a slightly different classification to a scientist in radiation. The above layers I've told you are commonly referred to though.

Question:I have a science project due this week and I have to make a 3-D model using non-food items. A different material for each layer is required and it must be a good representation of that layer. Does anyone have any suggestions? have a science project due this week and I have to make a 3-D model using non-food items. A different material for each layer is required and it must be a good representation of that layer. Does anyone have any suggestions? ALSO, I can't use any liquid or food. i have a styrofoam ball to start with. must use different material for each layer. the ehow.com project is using different colors of clay which is not what my teacher wants. whose class is your daughter in?

Answers:Inner core can be metallic, outer core a liquid, the mantle should be similar to honey, so use any non food paste, the crust must be solid

Question:Heyy guys :) i am doing the "Earth Layers" project for 8th grade science and i need help. I have the layers down and all of m materials but i cannot figure out how to do the scale. Something about cross multiplying by the radius of the bowl i am doing it in? Help :)

Answers:radius of the bowl divided by radius of the earth gives you the scaling factor that you need to use. Each earth layer is multiplied by this scaling factor. The tricky part will be laying in the bowl. Using modeling clay in different colors might be a way to do it. Good Luck

Earth Science - The Four layers And Spheres of Earth :A video created as a small project for my Earth Science class. The assignment was to create something showing that you understand the concepts of the chapter, and I chose to create a video. The video describes the four spheres that make up our planet: The Geosphere, the Hydrosphere, the Atmosphere, and the Biosphere. It also goes in to detail about Wether or not Earth is an open or a closed system, and the four basic layers that make up our planet. Plus a little bit about the magnetic field.
